I'm with tghobby, don't give it up if YOU enjoy it.
There's always going to be people hating on the internet.
I'm reminded of a comic from The Oatmeal. Scroll down to the section on Comments.

And at the same time, if you're creating anything, especially when you're first starting out, a lot of it is going to be mediocre (or even bad). Even without the ability to invest significant time, you will get better if you keep doing it.
My advice would be if you enjoy creating, then keep on doing it, stick your fingers in your ears (or eyes, since it's the internet) and ignore everything anyone says about what you create.
If you really want feedback, ask for it from someone (or at someplace, but theprocess forum isn't it) you trust to be constructive, but be prepared to hear that you need improvement. Everyone does.
